HV BOLTS NUTS
BS EN 14399-4 and DIN 6914 is to use thinner nuts
and shorter thread lengths to obtain the required
ductility by plastic deformation of the threads
within the nut. In Germany, the HV bolt assembly
is used in both preloaded and non-preloaded
applications and it can be argued that in the
event of failure by thread plastic deformation
the assembly still acts as a non-preloaded
assembly.
These assemblies are more sensitive to
over-tightening during preloading and therefore
require more site control. If severely over
tightened during preloading the mode of failure
by plastic deformation of the engaged thread of
the bolt assembly offers little indication of
impending failure.

Hex Bolts
Hex nuts (also referred to as finished hex nuts)
are available in ASTM A563-A and compatible with
low carbon steel bolts such as ASTM A307, ASTM
F1554 grade 36, SAE grade 2, and AASHTO M183. SAE
grade 5 and grade 8 nuts are also available in a
finished pattern. Since hot-dip galvanizing
typically adds 2.2 to 5 mils of thickness to the
threaded portion of a fastener, galvanized hex
nuts are tapped oversize to compensate for the
corrosion resistant coating on the bolts.
We manufacture complete range of Stainless steel
hex bolts and screws in the following grades,
stocks are readily available and we are
manufacturing bolts diameter from M-12 to M-72
diameter.

Hex Nuts
A nut designed specifically to thread on to small
diameter machine screws. They are typically
thinner than regular nuts with a finished side
for butting up against the surface that does not
need a washer.

Stainless Steel Fasteners
A Stainless Steel Fastener is recognized by a
helical ridge, known as a male thread or thread
just wrapped around a cylinder. A bolt or screw
is kind of fastener. Some screw threads are known
as female thread as they are designed to mate
with a complementary thread, some times in the
form of a nut or an object which has an internal
thread formed into it. Because other screw
threads are designed to cut a helical groove in a
softer material as the screw is inserted.
